178 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA 



C. melanospermus, but that has distinctly larger spores on the average, and a fimbriate 

 mouth. Miss Andrews (1. c.) says that the spores of the type of Nidularia stercorea 

 in Schweinitz's herbarium are 15.8— 18.7ju, and thinks it perhaps the same as C. Z,e- 

 sueurii var. minor Tul. We find the spores of the type to be 16.5-22 x 18.5-27^.

Cyathus rugispermus (Schw.) De Toni 



Plates 98 and 121 



Cups short goblet-shaped, about 4—5 mm. high and up to 8 mm. broad, the mouth 

 in youth convex, at maturity not flaring or fimbriate except that the outer spongy 

 layer projects a little farther than the inner layer and is minutely eroded; base narrow 

 the light brown mycelium holding firmly to a bit of earth ; outer surface deep chestnut 

 brown, felted-tomentose to moderately strigose; inner surface deep brown, shining, 

 not at all striate. Peridioles 1.6-2 mm. wide, smooth, black, shining, not concave 

 below, the funiculi represented only by a little central plug at the time found. 



Spores (of No. 7458) smooth, oval, thick- walled, 11.4-14.8 x 15-18. 5/*, borne as 

 usual in the genus. 



While the spores of our plants run larger than in the type, as given by Miss White, 

 other characters seem to fit well except for the darker outer surface of the former. 

 The species is near C. stercoreus, and Lloyd thinks they are the same. In all of our 

 collections of C. stercorals the spores, though variable, run much larger than in the 

 present species. Lloyd finds the spores of Japanese specimens to run as low as 16-24/x, 

 while for American plants he gives the spores as 30-40/i. On account of the different
